Both my husband and myself are having the same problem. I just left the Verizon store after receiving virtually no assistance with the problem. The rep turned the phones off, turned them back on, ran the My Verizon diagnostic which showed no problems and told us to come back if we have the problem again. I explained that turning phone off/on only fixes the problem for a little while, minutes, hours who knows! I even showed her this thread. She took the phone started reading the post, said let me try one more thing, closed the browser and said "well they want us to run the diagnostic, I ran it, if the problem returns come back" Verizon this is UNACCEPTABLE!!!!!!!
